I have a disagreement with a buddy of mine about his mph on a track. His stock no pipe or any mod Busa is getting a 157 and 158 mph sometimes on the 1/4. I said the track mph is off since I ran almost a consistent 145/146 mph on my last Busa with a pipe and mapped.Most of my research shows mid to low 140 area on a all stock bike. The track had my bike show a 161 before but only the one time. Doea anyone have a bone stock gen 2 Busa above the 150 mph in the 1/4. I haven't seen the slip but he is in the real low 10 's.
